2.2 SHIPMENT AND TRANSIT

The machine has been assembled, operated and inspected
at the factory. Upon arrival at the fi nal destination, the
entire machine must be checked for any damage which
may have occurred during transit.
With the method of packaging used, the machine should
arrive in excellent condition. THE CARRIER IS RESPON-
SIBLE FOR ALL DAMAGE IN TRANSIT, WHETHER
VISIBLE OR CONCEALED. Do not pay the freight bill
until the machine has been checked for damage. Have
the carrier note any visible damage on the freight bill. If
concealed damage and/or shortage is found later, advise
the carrier within 10 days and request inspection. The
customer must place a claim for damages and/or short-
ages in shipment with the carrier. Stoelting, Inc. cannot
make any claims against the carrier.

INSTALLATION INSTRUCTIONS

PRIOR TO INSTALLATION
A. Locate a copy of the service contact fi le (info.txt).
B. Modify the info.txt fi le with information from the
service company using the instructions in the fi le.
C. Put the service contact fi le onto the root level of
a USB fl ash drive (do not put the fi les into any
folder).
INSTALLATION
A. Uncrate the machine.
B. Install the four casters. Turn the threaded end
into the machine until no threads are showing. To
level, turn out casters no more than 1/4" maximum,
then tighten all jam nuts.
C. The machine must be placed in a solid level
position.
Accurate leveling is necessary for correct drainage
of freezing cylinder and to insure correct overrun.
D. Machines with air cooled condensers require a
minimum of 6" (15,2cm) space on all sides and
back for proper circulation.
In order for the condenser fan motor to work the
left side needs to be connected to a power source.
E. In air-cooled machines, use a voltmeter to measure
incoming voltage. If the supply voltage is 215 or
less, remove the right side panel and move the
voltage selector toggle switch to the 208V position.
Supply voltage must be checked to make sure the
fan motor operates properly.
F. Machines that have a water cooled condenser
require 1/2" NPT supply and drain fi ttings.

2.4 INSTALLING WIRING

A. Refer to the nameplate on the side panel of the
machine for specifi c electrical requirements. Make
sure the power source in the building matches
the nameplate requirements. Bring the wires into
the junction boxes through the access holes in
the bottom rear of the freezer.
Three phase freezers in areas of unbalanced elec-
trical loads require special attention when connect-
ing input electrical power. The unbalanced leg of
power (called wild or high) must be connected to
L2 in the junction box.
